Early JRDGs were actually not hot at all. The distortion was more like a fine fuzzy texture. Good enough for HT but not music IMO. The new D-amps are nothing like the early Ts, Ices' and Hypex'. The new Bel Cantos and CIAs will give many linear amps a good run for overall value I think. I haven't heard the H2Os but I've gotten very good feedback on them from a couple of very @nal retentive friends of mine in the US.
